3 Major Activities of Flood WG Preparation of Generic template for demonstration projects in GEO on use of satellite information for flood risk Management (led by Prof. Herath) Demonstration projects Identification of member countries needs and resources for capacity building shifted to capacity building WG Proposal to 2007 Annual Regional Call for Proposals (ARCP), APN (Asia-Pacific Network for Global Change Research) Approved for FY & To enhance demonstration projects through holding meetings (ICGs) and workshops (GFAS/IFAS Validation WS) Contributions to 4 th APHW (Beijing) and GEOSS-AP activities (typhoon and cyclone session)

4 Indonesian Seminar and Workshop on the Use of Satellite Base Information in Flood Risk Management (Jakarta & Bandung, July 2008) From Dr. Loebis s presentation

5 2-year Project Proposal to 2007 Annual Regional Call for Proposals (ARCP), APN With in the context of the APN support the flood research project addressed the following overall objectives: 1. Converting observations and data, both through space borne platforms and data integration initiatives, to usable information for flood reduction. 2. Improvement of quantitative forecasts for coupled precipitation - floodforecasting systems. 3. Facilitate risk assessment through the provision of scenarios and data for exposure estimation. It is essential to enhance and utilize regional cooperation to achieve these objectives using the resources and knowledge available at various specialized institutions. Training programs on the use of tools and data will form the basis for to capacity development activities. Approved, with the budget of USD 42,000 for Oct Sep (1 st Year) & for Oct Sep.2010 (2 nd year)

6 Goal of APN-ARCP (Flood) To build up a scientific basis for sound decision-making and developing policy options for most suitable flood risk management for each country and region in Asia, through the full utilization of new opportunities on global, regional and in-situ dataset under the scheme of AWCI (contributing to GEOSS)

8 Progress Report for APN-ARCP (1 st Year, FY ) Feb

9 Workshops for Validation & Application of Global Flood Alert System (GFAS) & IFAS 1) 3-8 October 2008, 2) 3-7 August 2009 Contents The purposes is to build capacities in the countries to be able to undertake hydrological prediction/ forecasting in relatively ungauged catchments, to share local experiences and subjects, and to consider next actions From 1) Ethiopia, Zambia, Cuba, Argentina, Bangladesh, Guatemala, Nepal (7countries) 2) Bangladesh, India, Indonesia, Lao PDR, Nepal & Vietnam (6 countries)

10 Activity plan for 2 nd year of APN-ARCP (flood) of the 1 st -phase of demonstration project (FY ) 2-1. To continue in-situ observations as an experimental basin for each study basin area 2-2. To archive observational and analyzed data coupled with global/regional data 2-3. To make tentative validations of the systems and/or scenarios 2-4. Identification of the subjects to improve the demonstration systems 2-5. Technical supports and cooperation to validate the above demonstration systems 2-6. Investigation of the needs and requirements in relation to flood risk management and the above activities from operational point of view (esp. capacity building) 2-7. Summarizing a report of the ARCP project including proposals on policy options

11 Activity plan in APN-ARCP (flood) after Oct. FY2010 as the post-phase = 2 nd phase of the demonstration project P-1. To continue in-situ observations to get enough validation data P-2. To improve the demonstration systems/scenarios and to make final validations of them with the archived & analyzed data P-3. To develop capacity building tools for shifting the demonstration systems to operational ones for the next-stage AWCI.

12 Actions to be taken: (short-term, 1/2) How to collaborate with some specific demonstration projects through coordination? Information exchange and mutual consultations among Flood WG meetings and communications To share the findings and results of the application of state-of-the-art models in demonstration projects Which kind of data do you need to promote activities? Long-term historical extreme data (flood and low flow) such as annual maximum (minimum) are to be shared for climate-change impact analysis. The combination of rainfall and natural (not affected by any regulation) river flow data of such events is preferable. If streamflow is not available, rainfall data only is also acceptable. DEM data are important for flood & inundation analysis. Some reports mentioned the quality of ASTER-DEM data seemed insufficient. We should seek for any other data sources or make up our own methodology to create such DEM data to meet our requirements. The quality of in-situ hydrological data is crucial for us. The information of our practices (technical standards) especially for flood discharge measurement method and its data quality-check method (both on site and off site later) should be shared. Mr. Fukami will propose the points to be shared. The information of our practices (technical standards) to determine design flow (and/or rainfall) for planning river projects, dams, weirs, etc. should be also shared. Dr. Rakesh Kumar will propose the points to be shared.

13 Actions to be taken: (short-term, 2/2) Which types of Capacity Building do you need? Technologies on state-of-the-art hydrological models such as UT- GBHM, ICHARM-IFAS(PWRI & BTOP), etc. ## A table to show and compare the characteristics of each model should be arranged for reference by Mr. Fukami and Dr. Saavedra. Rainfall forecasting (downscaling from global numerical weather forecast data) How to focus Flood WG activities on CCA in cooperation with Demonstration Projects? To consider the characteristics & the possible change of flood characteristics (frequency, magnitude, etc.) induced by climate change in the demonstration projects How to collaborate with Water quality WG in the context of climate change adaptation? To provide Water-Quality WG with the information with the change of flood characteristics (frequency, magnitude, etc.) To include water-quality resource person to capacity-building seminars on hydrological modeling technologies

14 Actions to be taken: (mid-term) To promote each demonstration project of each member country according to its own specific objectives and the dissemination of its achievements through papers/presentations. To identify and share any problems to promote demonstration projects, and to support how to cope with them through our mutual cooperations, so that we will figure out what the next action should be, toward their operational uses To ask each AWCI member to give us any materials, including the information of presentations & submissions of papers, to summarize final achievements for two-year activities related to flood issues for the APN-ARCP project around December 2010 (TBD).

15 Thank you for your attention! Let s take advantage of AWCI network and activate our mutual communication & cooperation more and more! 15
